Shandong Rare Technology Development Co., Ltd. (Rare High Tech) adopts a unique graphene nanophase change material (national patent 202211637322.8). It uses the amphiphilic biomass dispersing and stripping agent's conjugated hydrophobic end to intercalate and strip graphene, while the hydrophilic end forms a long-term stable high-purity graphene dispersion with the solvent. Through independent solid-liquid mixing technology, the graphene dispersion is uniformly adsorbed and efficiently complexed with cellulose substrates and PET (PA6) substrates, and a high-quality multi-functional graphene modified new material for textiles with good biocompatibility and ultra-high thermal conductivity is prepared——Qimai® graphene superconducting fiber/yarn.

【Product Functions】

Tested by national authoritative testing institutions and feedback from scientific practices, Qimai graphene products have excellent health properties such as releasing far infrared rays, ultra-high thermal conductivity, long-lasting antibacterial properties, antiviral activity, high antistatic performance, anti-ultraviolet performance, and green preparation.

1. Release far infrared rays

At a low temperature of 25-35℃, graphene has excellent normal emission and absorption promoting effects on far infrared rays with a wavelength of 6-14μm. This band of far infrared rays is hailed as the "life light wave" by scientists, which can assist in promoting microcirculation. Tested by national professional testing institutions, the normal far infrared emissivity of Qimai® graphene superconducting fiber/yarn can reach more than 90%.

2. Ultra-high thermal conductivity

Graphene is the material with the highest thermal conductivity so far. Tests show that Qimai graphene has excellent thermal conductivity. Under the same heat source, its rapid temperature conduction capability is more than 30% better than that of conventional materials. In a warm environment, body heat can be rapidly conducted and stimulated through graphene fiber materials, forming a "heat storage cabin" warming effect. In an open environment, body heat can be rapidly dissipated through the fiber materials, forming a "heat radiator" effect. Qimai® graphene superconducting fiber/yarn is an excellent "two-way temperature regulation" material.

3. Long-lasting antibacterial properties

Scientific research has found that when Escherichia coli and Staphylococcus aureus are exposed to graphene, the stress on the edge film of the graphene layered nanosheets can directly pierce the bacterial cell membrane, causing the leakage of its internal RNA (ribonucleic acid) and leading to the death of the bacteria. In addition, due to the large specific surface area and strong adsorption capacity of graphene, it can adsorb phospholipids, the components of the cell wall, preventing bacteria from reproducing normally. At the same time, the powerful far infrared effect of Qimai graphene can assist in promoting microcirculation, thereby activating skin immune cells, strengthening the phagocytic function of leukocytes and reticuloendothelial cells to achieve the antibacterial purpose, and the antibacterial effect does not decay after multiple washes.

4. Antiviral activity

Traditional antiviral materials such as metal materials, chemical drugs, high temperature and ultraviolet irradiation can inactivate viruses, but there is a risk of cytotoxicity causing harm to the human body. Graphene's unique nanoscale edges, large specific surface area, surface functional groups and photothermal catalytic effect bring broad-spectrum antibacterial and antiviral properties and the ability to effectively "inactivate" viruses. In addition, Qimai graphene's special band structure and strong adsorption characteristics can easily "catch" bacteria and viruses, with the active feature of "catching" + "killing".

5. Anti-ultraviolet performance

Ultraviolet irradiation with a wavelength range of 290-400nm will cause the skin to produce a large number of free radicals, leading to peroxidation of cell membranes and causing melanocytes to produce more melanin. Qimai® graphene superconducting fiber/yarn can effectively shield ultraviolet rays and convert them into far infrared rays. It can not only protect the skin from sunburn and reduce the risk of skin cancer, but also achieve the purpose of health benefits.

6. Green preparation

The preparation of Qimai® graphene superconducting fiber/yarn uses amphiphilic biomass dispersing and stripping agents, and uses biological technology instead of chemical agents to solve the problems of graphene sheet agglomeration and unstable performance during processing. While greatly improving product quality and functions, it reduces the consumption of production resources and realizes green, healthy, low-carbon and safe production.

【Application Fields】

Qimai® graphene superconducting fiber/yarn is widely used in special equipment, aerospace equipment, outdoor equipment, sports apparel, underwear, home textiles, hygiene products, protective supplies, beauty products, functional protective gear and other product fields.
